LEMON M. REED, OF CLEVELAND HEIGHTS, OHIO, ASSIGNOR TO HATTIE E. GYN, F

CLEVELAND HEIGHTS, OHIO. l

.SPRING-SEAT.

citizen of the United States, and residing at Cleveland Heights, in the county of Cuyahoga and State of Ohio, have invented a new and useful Spring-Seat, of which the following is a speciication. j

This invention relates to improvements in spring-seats, and pertains more especially to a spring-seat comprising two vertically spaced and oppositely arranged substantially horizontal plates the lower of which is adaptedV to be carried by a supporting member, and also comprising springs employed in supporting the upper plate from `the lower plate, and furthermore comprising means for guiding` the upper plate rela.- tively to t-he lower plate and for .maintaining'said plates in parallel relation and directly oppositeeach other.

One object of this invention is not only to have said guiding means permit descent of the hereinbefore mentioned upper plate against the action of said springs without the movement of any portion of said means below the aforesaid lower plate, and to have said springs spaced circumferentially of the space between the central portions of the plates, but to have said guiding means arranged wholly in said space and composed of members having such relative arrangement that the plates are relatively movable to an adequate extent and that a strong, durable and simple connection is provided between the plates for maintaining said plates in parallel relation and directly opposite each other during relative movement of the plates against the action of the springs.

VAnother object is not only to provide each plate with vertical guiding members projecting toward and spaced from the other plate but to so connect said guiding members together that each guiding member will be helpful in steadying the other guiding members."

With these objects in view, and to attain any other object hereinafter appearing, this invention consists in certain features of construction, and combinations. and relativear 1angements of parts, hereinafter described in this specification, pointed out in the claims, 4and illustrated in the accompanying drawings.

In saiddrawings, Figure l is a side elevation, in central vertical section, of a springspecification of Lettersratent. Patented Oct 12, 1920,

Application filed December 27, 1919.

Serial No. 347,824.

Fig. 2 is a Fig. l. Figs. 3 and t are drawn on a larger scale than Figs. 1 and 2.

Referring to Figs. l and 2 of said drawings, 5 indicates the upper portion of a bracket adapted'to be carried by the framework or body Vof a tractor or other vehicle or machine, and said bracket has a rearwardly projecting arm 6 on which my improved seat'is shown mounted. Said seat comprises two vertically spaced and directly oppositely arranged substantially horizontal metal plates 7 the lower of which is shown mounted directly on the bracket-arm .6 and secured to said arm in any approved manner. An even number of vertically arranged helical springs l0 are interposed be-l tween the plates 7 Vand spaced circumferentially of the space between the central portions of the plates and support the upper plate from the lower plate. The seatproper 9 is applied to the upper plate in any approved manner. Improved means for guiding the upper plate in relation to the lower plate and for maintaining said plates in parallel relation and directly opposite each other, during any vibration to which the lower' plate may be subjected, are shown as comprising two horizontally spaced guiding members 11 which project vertically downwardly from the upper plate, two horizontally spaced-guiding members l2 which project vertically upwardly fromthe lower plate, and a sleeve 13 which loosely embraces said guiding members and is arranged centrally between and spaced preferably equidistantly from the plates. The guiding members l1 and l2 correspond in thickness and dimensions andare preferably circular in cross section. The upper guiding members l1 are secured to and rendered rigid with the upper plate in any approved manner, vand the lower guiding members 12 are secured to and rendered rigid with the lower plate. Each guiding member of each plate is spaced at its free end fromthe other plate, and preferably all of the guiding members are arranged in the space between the central portions of the plates. y Preferably said guiding members are spaced forwardly and rearwardly,

and preferably the guiding members of each plate alternate with the guiding inembers of the other plate. rfhe member forming4 the sleeve 13 has a vertical hole 14 for each guiding member, and said hole extends vertically through the sleeve; The sleeve illustrated therefore extends iorwart ly and rearwardly 'of the seat and is provided with four holes 14 spaced Jiiorwardly and rearwardly of the sleeve. ward holeY 111 is engaged by the rearward guiding member of the lower plate'and the forward intermediate hole is engaged byv the forward Uuidinomember of said lower plate, and therefore the most forward hole and the rearward intermediatehole in the sleeve are engaged respectively by the ror- Vward guiding member aiidi'earward oruid- .ing member ofrt'he upper plate.'y *ach Vsaid guiding' member and projects into vertical slots 16 iormed'in the sleeve at oppo. site sidesV respectively or said end portion of said guiding member and consequently at opposite sides respectively of the hole en` Agaged by said guiding member, as shown in Figs. 3 and t. The'slots lowhich are eiigaged by a pin 15 of an upper guiding member 11 (seeFig. extend from a point `approiiimately central between the bottom and top oli-the sleeve to and are open at Vthe bottom of the sleeve and have vdownwardly iacing upper end walls 17 which are overlapped by said pin,.and obviously said pin and said slots are arranged to permit move- Vment of said uppery guiding member downwardly independciitlyk Voi the sleeve, and saidpin and said walls of said slots con-l stitute means for preventing movement oi thev sleeveA downwardly independently ot said guiding member in the upper and normal position of the upper plate. The slots 1G which," engaged by a pin 15 of Va lower guidingmember 12 (see Fig. l) extend from apoiiit approximately,central between the top and bottom of the sleeve vto andare Vopen atthe top of the sleeve and have upwardly facing lower end walls 18 which are overlapped by saidV pin, and obviouslysaid pin and saidslots are arranged to permit movement of said lower guiding lmember upwardly independently of the sleeve, and saidpin and said walls of said slots constitute-means for preventing movement oil the sleeve upwardly independently of said guiding member in the normal rela'- tion of the plates. The sleeve (see Figs. 1V

and 2) is provided with two arms i2()V pro- The most rear,-Y

jecting forwardly and rearwardly respectively, and the relative arrangement oi' the partsis such that adjacent each arm 2O is a spring 1G and said arm extends between two adjacent coils of said spring centrally between the ends of the spring. 'lhe springs adjacent the arms 2() are diametricaliy opposite, and said arms and said springs are helpful in holding -tlie sleeve in position during the assemblage of the parts, as said springs can be applied to the lower plate before the application of the remaining springs. Preferably before the application or said remaining springs the' lower plate, the lower guiding members 12, the sleeve 13,

the two springs adjacent the arms 20, the` upper plate and the upper guiding members 11 are assembled, and it will be observed that said arms and the last-mentioned springs cooperate in ed'ecting downward movement of the sleeve as desired independently of the guiding members of the lower fplate during'the compression of the springs. by the descent of the Vupper plate independently of the lower plat TWhat l claim is- 1. 1n a spring-seat, the combination, with twovertically spaced substantially horizon tal plates the lower of which is adapted to be carried by a supporting member, Veach plate being provided with a guiding memberv projecting toward and spaced iromthe other plate, and springs supporting the upper plate Jfrom the lower plate, the guiding members of the pla-tes being arranged in ditlerent vertical planes respectively, of a sleeve loosely embracing said guiding members and arranged betweenV and spaced from the plates, the guiding member oi' the upper plate being movable downwardly independently of the sleeve, the guiding member of the lower plate being movable upwardly independently of the sleeve, said sleeve and the guiding member ofthe upper plate having means for preventing movement of the sleeve downwardly independently oi' said guiding member in the upper and normal position of the upper plate.
